The occurrence of taste and odor (T&O) is one of the biggest problems that drinking water utilities face. 2-methylisoborneol (MIB) and geosmin, present in many surface waters, are thought to be the most common sources of taste and odor. They cause objectionable musty and earthy odors, which are two of the most frequently reported complaints to utilities. Granular activated carbon (GAC) adsorption is one process that has been shown to be effective for the removal of a broad range of organic contaminants. However, in spite of widespread GAC application, relatively little research has been conducted to evaluate GAC removal of MIB and geosmin. As a consequence, there are no widely accepted predictive models available to aid in adsorber design. In this study, the performance of the GAC process for MIB control was evaluated under a range of conditions. Influent MIB and natural organic matter (NOM) concentrations, NOM preloading or GAC age, adsorber contact time, and GAC size were all found to strongly impact performance. Based on the GAC performance test results, models were developed to predict the bed volumes to target effluent MIB concentrations based on influent and design parameters. The remaining GAC bed life under intermittent MIB loading could also be determined. In addition, a MIB control decision support system (MDSS) was developed integrating other potential alternative processes. The processes include adsorption, oxidation, biofiltration, membranes and a hybrid system. The MDSS consist of two major functions: (1) modeling tools which enable the simulation of these processes under a range of alternative scenarios, and (2) cost analysis, which is designed to aid utilities in process selection. The MDSS can help utilities establish a site specific strategy for T&O control in terms of design and operation.Subjects--Topical Terms:
